It does, but we do need to say what gets passed. jvm arguments, in particular, would be very useful. The problem here is that it seems that shells are inconsistent with how they handle arguments on the first line. This is specifically called out as a portability problem in [1]. That makes it difficult for the main Java launcher to handle these arguments. It would be wrong to make a general change to the Java launcher to reparse arguments containing spaces as individual options.

OK, I see what you mean. I had thought that Python did this properly, but I just tried it and it doesn't work. Well, it works kinda-sorta but exactly one argument can be passed on the command line. Eww. :-)
